4.1: Preliminary Setup

The network used to test the driver should include at least:

The hardware on which the driver is to run. It makes testing much easier if you can run a debugger to control the operation of the target machine.
An Ethernet network analyzer or a workstation with an `Ethernet snoop' program such as ethersnoop or tcpdump.
A workstation.

During early debug, you should consider putting the target, workstation, and snooper on a small network by themselves. This offers a few advantages:

There is less traffic to look at on the snooper and for the target to process while bringing the driver up.
Any serious errors will impact only your small network not a building or campus network. You want to avoid causing any unnecessary problems.
Test traffic is easier to repeatably generate.
Performance measurements are not impacted by other systems on the network.
